DUMP-CAR.

Specification of Letters Patent.

' Patented May 11, 1909.

Applicationfiled March 13, 1908, Serial no. 420,992.

To all whom it may concern:

Be. it known that I, THOMAS H. STAGG, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and the State of Ohio, have invented certain new-r and useful Improvements in DumpOars, of which the following is a specification.

My invention relates to improvements in dump cars and has especial relation to the means for holding the cor on the lowered or dumped side of the car" in elevated position while the car bed or body is carried to its dumped position, whereby the lading is permitted to be discharged; it comprises essentially an arm dependlng loosely from the car, a guide for said arm, and a member against which the arm may en age at its lower ends to prevent its further ownward movement, g

whereby the door structure is held aloft.

It is not contemplated that the arm member should be attached except adjacent to its upper end, and being pivoted to swing freely and to play loosely in the guide member, it is always properly positioned to be actuated to perform the function of holding the car door aloft when the car body or bed is given a dumping. movement.

' In the drawings which are hereto attached and are hereby made a part of this specification, Figure l is an end view of a car having my improvements thereon, the positions of i the various parts when the car bed is dumped being shown in dotted lines Fig. 2 is a side elevation of my improvements in place on a car.

Referring to the drawings in which the same numeral designates the same part throughout, 1 is a car bed )ivoted at 2' to swim laterally, and providec with side doors 3 an 4 hinged at 5 and 6 respectively to the arms 7 and 8 respectively, the latter being pivotally supported on the car body 1 at 9 and 10 respectively. The gusset plate 11 is mounted upon the arm 8 to hold the door 4 in proper osition when opened to return to,

certain loc ng engagement with the hook 12 when the-oar bed is again righted, as may be seen in Fig. 1.

Pivoted at 13 to the arm Sis the depending arm or member 14 having its lower end free or unattached; a swinging casing or sleeve or guide member 15 is mounted upon the car understructure at 16, and therethr'ough is inserted the arm 14. Also mounted pivotally 1 position is determined by that of the guide i member by being carried thereby as shown in i .Fig. 1 on the left when the arm 14 is operated tomaintain the door in elevated position; i this is accomplished by the pin 17 on the guide or sleeve 15, which carries the stirrup with the guide when the lower end of the guide is swung toward the center of the car, which takes place on the side of the car on which the lading is dumped, but on the opposite side of the car the position of the stirrup or stop member is undisturbed. This stirrup 17 is therefore always in position to receive the lower end of the arm 14 to support the same whereby the door is prevented from traveling downwardly with the car bed when the latter is dum Jed.

If the car bed edumped toward the left as indicated in Fig. 1, the parts will assume the guide member 15 not being shown in its rotated position to avoid confusion due to numerous dotted lines. tion of movement and the position it would assume may readily be understood, especially by reference to the guide memberlS on the opposite side of the car. When the arm 14, moving with the car, engages the stirrup 17 with its lower end, said arm is prevented 4 is held aloft in the manner shown in dotted lines in Fig 1. The lading is now free to discharge from the car bed. Upon righting the car, the bed is moved upwardly until it engages the door 4 and carries it along thereby causing the arm 14 to be witlulrawn from contact with the stirrup 17, and causing the sleeve to be swung back to its normal position.

The arm 14 is seen to have connection with the door at one of its ends and to move therewith, while its other end is free joints or hinges in the arm 14 are completely avoided, and the construction is composed of very few parts of great simplicity, which are not likely to get out of order in use.

What I claim is:

1. In a dum car having a swinging door construction t iereon, a member pivotally connected therewith at one of its ends and having its other end free, a pivoted guide for saidmember and a stop pivotally associated with said guide and arranged to move with the guide to lie in the path of said member l-the positions indicated by the dotted lines,

from moving farther down, and as the tilting i movement of the car bed, continues, the door However its direc- 4 l lree, a swinging guide for said arm, and a i thereon at one end and havingits other end 4 In a dump ear having. a swinging door whereby said door is maintained in an ele- |construet1on, an arm prvotally connected vated position on the side toward which the car is dumped. V i

2. In a dump ear having aswinging door construction, an arm pivotally mounted adapted to receive said arm to guide the thereon at one end and havmg' its other end same, and a stop member arranged to be engaged by the free end of said arm to limit the downward movement of said arm, Whereby said door is maintained in elevated position as the car is dumped.

In testimony whereof I aflix my signature in the m'esenee of two witnesses.

swinging stop member to limit the down Ward travel of said member.

3. In a dump ear having a swinging door construction, an arm pivotally mounted free,'a swinging guide for said arm, and a swinging stop member to limitthe downward travel of said member, as said 'car is dumped, whereby said door is maintained in elevated position.
